Fig. 3 shows a side elevation of the center frame which supports the teeth Vbetween the cultivator-wings, detached therefrom.

A A represent the supporting-Wheels.

B is a beam supported on a suitable framework above the axle of the supporting-wheels.

C C is the tongue, preferably attached to the beam B at the rear end of the tongue, as

shown in Fig. 2.

Attached to thetongue in front of the driving-wheels are the cross-pieces F and E, which cross-pieces, in combination with the tongue, form a supporting-frame for supporting the r', and bar F.

front ends of thewings ,n and center toothframe.

K K are two elliptical frames, each frame encircling the upper part of one of the wheels. These frames form the wings of the cultivator and support the spring-teeth 2 2 2, dac., which teeth are attached in the manner hereinafter described. Each of the wings K is supported at the-front end by means of the lug 1', pivot The bar F is attached to the cross-bar F, and is provided with a series of holes for the reception of the pin or pivot r. The front end of the frame K may be adj usted means o f grips and nuts.

vertically by means of the pin o" t0 any desired point. The rear end of each frame K lis pivoted at e to the connecting-rod e2, which rod is connected by the link a to the leverarm 3. The lever-arm 3 is in the shape of a bell-crank, and is rigidly attached to the lever L in the manner shown in Fig. 8. A toothed segment 4 is rigidly attached to the cultivatorframe, 4and a stop operated by the latch 5, rod 5', and spring 6 engages with the teeth of the segment 4 and holds the lever and connecting-rods invany required position.. The lever as arranged in the drawingslifts the rear ends of the frame K when said lever is pushed forward and lowers it as itis pressed backward. The cultivator-teeth on the rear of the frame K may not only be adjusted to any required depth, but can be raised entirely from the ground, if required.

The two frames K K are constructed and operated alike, and a description of one will serve for both. The frames K K are connected by means of the bar or rod c', pivoted to the pins at c c, as shown in Fig. 1. The wings or frames K K are also connected by a frame I, having a projection b, that rests on the connecting-bar c. jection h of metal and attach it to the frame I by grips, as shown. From the front end of I are two arms extending to the supports F', and attached thereto by means of draw-rods S S on one side at t t.

Depending from cross-piece E are two supports, one of which is shown by E in Fig. 2. Theseisupports are provided with holes for the reception of a clip 0n the whiiiletree, allowing for a vertical adjustment of the whifiietree. The supports F and E are connected by means of rods S S, which engage with the holes in E and F.

The seat H is of any suitable form, and is supported on the bars D D, as shown.

The teeth 2 2 2, ctc., and 2 2 2 are attached by means of the device shown in Figs. 5 and 6, in which 12 represents a concave piece and 12 a convex follower. The upper curve of the tooth corresponds with the curve of 12 and 12', and is placed between 12 and- 12 and securely clasped in that position by attaching the teeth they can be singly ad- By this method of' I prefer to construct the pro- IOO jnsted to any position by simply loosening the nuts `and turning the tooth in its seat and again tightening the nuts.

G represent-s the whiletree.

Having thus described myinvention, what I claim to have invented, and desire to secure by Letters Patent, is-

l. In a cultivator, the combination, with an axle and a supporting-frame, of an adjustable tooth-bearing frame suspended from the supporting-frame above the axle and surrounding the upper portionV of the cultivator-wheel, substantially as described.

2. In a cultivator, the combination, with a tooth-bearing frame adjustably suspended above the axle and surrounding the upper portionof the cultivator-wheel, of a lever, a lever-crank, and a connecting-rod for raising and lowering the rear end of said tooth-frame,

substantially as described. Y

3. In a cultivator, the combination, with a supporting-frame, of twoelliptical tooth-bearing frames surrounding the cnltivator-wheels and suspended from the supporting-frame, a

connecting-rod c', pivot-edV to said framesin.

rear of the axle, and. levers, toothed segments, and connecting-rods for raising and lowering the rear ends of either of said toothbearing frames and retain them at any desired elevation separately, substantially as described.

4. In a cultivat0r,tbe combination of asupporting-frame located above the axle, the

,swing tooth-bearing frames K K, surroundin g the upper portions of the cultivator-wheels, a pivoted cross-rod c', connecting said swingframes at theI rear of the axle, a central toothbearing frame pivotally supported above the axle between the swing tooth-bearing frames and having its rear end resting on the crossrod that connectssaid frames, and levers for `vertically adjusting the rear ends of said frames, substantially as' described'.

In witness whereof I have hereunto set my hand' andsealV in the presence of' two Witnesses.
